Sample Output

Enter a list of shapes - 'done' to end

Enter the shape's color (or 'done')...
red
Enter shape type...
circle
Enter the radius...
5.0

Enter the shape's color (or 'done')...
green
Enter shape type...
rectangle
Enter the length and width...
2.0 4.0

Enter the shape's color (or 'done')...
blue
Enter shape type...
square
Enter the length of a side...
3.0

Enter the shape's color (or 'done')...
done

The list of shapes entered...
red circle with radius of 5.0 and area of 78.53975
green Rectangle with length of 2.0 and width of 4.0 and area of 8.0
blue Square with side length of 3.0 and area of 9.0

Sorting shapes into order by area...
